Product Description

Description
SLC-VS904( Silcat VS-904 from Momentive)is a crosslinking system (silane, peroxide and catalyst) specially developed low/medium voltage cable.
Moisture content of the PE resin must be less than 200 ppm. In hot and humid countries pre-drying of the resin at 70c by means of an air desiccator is highly recommended.
Grafting: Optimum addition levels for a given application must be determined experimentally. Data collected on Nextrom extruders indicate that the dose levels of SLC-VS904 ( Silcat VS-904 from Momentive)should be between 1.3 and 2.0 wt %.
Temperature profile setting of the extruder:
- Barrel 150/150/150/190/200/200/210c
- Head and die 210c
- Screw 80-100c
Crosslinking: Rate of cure is dependent upon time, temperature and thickness of the layer and available moisture. Sufficient crosslinking can be achieved by any of the following methods:
- Immersion in water at 80-90c, or
- Exposure to low pressure steam at 105c, or
- Exposure to steam at atmospheric pressure
